What undb is

undb is an open-source no-code database and backend-as-a-service platform based on SQLite. It provides table management and formula fields, along with a browser playground that does not require an account or installation. Its README lists OpenAPI REST support, and the project publishes OpenAPI documentation. For deployment, users can run it with Docker or build it from source; documented database providers include SQLite, Turso, and PostgreSQL. Its environment documentation also describes GitHub and Google OAuth, local storage, MinIO and Amazon S3 storage, and SMTP through Nodemailer and Mailgun. Playground data exists only in browser memory, so it is lost when the page is refreshed or closed. The project is free and open source, although its terms describe free and paid services and note that paid services may limit storage and OpenAPI request frequency. Its privacy policy says data is encrypted in transit using HTTPS and describes technical and organizational safeguards. The GitHub repository was archived on September 22, 2026, and says the project moved to Teable. That archived status is a key consideration for anyone evaluating undb for a new deployment.
